The ozone layer is not in danger especially from CO2 . The ozone layer is at the very edge of space and nothing can get that high except hydrogen. Now CO2 is a very heavy gas and actually lays on the ground . It is so heavy they use it to put out fires,as it smothers fire.

Answer 3

- limitation of ozone...

The Montreal Protocol on Substances That Deplete the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. The treaty was opened for signature on September 16, 1987 and entered into force on January 1, 1989. Since then, it has undergone five revisions, in 1990 (London), 1992 (Copenhagen), 1995 (Vienna), 1997 (Montreal), and 1999 (Beijing). Due to its widespread adoption and implementation it has been hailed as an example of exceptional international cooperation with Kofi Annan quoted as saying it is "Perhaps the single most successful international agreement to date...".
